The field of application is for removal of air in connection with transport of polluted air, hazardous gases and dust. The products are also in accordance to the international guidelines for non-sparking fans in marine environments.

The ZerAx® AZL are unidirectional axial flow fans for installation in air handling units (AHUs). The primary application is for new installations. Depending on the kind, layout and construction, the fans can be used for retrofitting existing installations.

The ZerAx HT AZL smoke exhaust fans with integrated inlet cones are for conventional ventilation and operation during fires in car parks, tunnels and all types of buildings. The design is tested and approved to meet requirements for smoke exhaust in combination with frequency converters.

Compact and unidirectional car park jet fans (AZT) with adjustable outlet and low fan height.

Fans of the AZT type are especially robust, compact and perfect for car parks, small tunnels and service yards. The jet fans have optimal capacity, long life spans, reliable operation and are service-friendly.

The fan casing is round with an integrated inlet cone and an adjustable outlet cone. This minimises the inlet loss and provides optimum control of the outlet airflow. The fan has guide vanes to improve the aerodynamic efficiency. A wire guard is mounted on the inlet cone. The installation is simple due to an innovative and new easy click-click design. Once the base plate is mounted to the ceiling, the fan is simply clicked in position and secured with fasteners.

The impeller consists of a ZerAx hub with aluminium impeller blades in pre-determined pitch angles. The impeller sits directly on the motor shaft. All ZerAx fans are statically and dynamically balanced in accordance with VDI 2060, ISO 1940 Class Q 6.3.

The motors are two-speed 3x400V or 3x380V, both in 50 or 60Hz versions. Motor protection is min. IP55 in accordance with IEC 34-5. The jet fans have external terminal boxes. Damping of vibrations is unnecessary due to the balanced and stable running of the ZerAx fans.

The fan casing is of pre-galvanised sheet steel, which can be optionally powder coated in any desired colour. In standard execution, the jet fans meet the requirements for operation in unheated, low corrosive environments according to DS/EN ISO 12944-2, corrosion category C3.

The standard operating temperature is from -20 to +55°C. The fans for are certified for removal of hot smoke according to the EN 12101 part 3 in the classes F200120 and F30060.

F200120 fans tested at 300°C / 120 min
F30060 fans tested at 300°C / 120 min

The ZerAx AZN are unidirectional axial flow fans for conventional and industrial use.

Optionally the ZerAx AZN fans are available as smoke fans. The ZerAx AZN smoke exhaust fans are for conventional operation and operation during fires in carparks, commercial and industrial buildings, tunnels and more. The design is tested and approved to meet requirements for smoke exhaust.

The ZerAx AZW are extra durable unidirectional axial flow fans for marine use. The main characteristic is the very strong 10 mm thick fan casing, which is an expressed requirement from the marine industry and which makes the AZW suited for rough conditions.
